2 Claims.

This invention relates to certain new and useful improvements indisposable razors.

lhe primary object of the present invention is to provide a disposablerazor of a type suitable for travelers, soldiers, and the like which islight in weight, requires a minimum of storage space and which is soeconomical in construction, comparing most favorably to the currentprices for razor blades, that it may be disposed of after a singleusage.

It is a further object of the present invention to provide a disposablerazor of independent two-part construction having a handle member and ablade holder which are adapted for interfitting engagement when therazor is in operative position and for disposition of the blade holderwithin the handle member for protecting the blade when the razor is ininoperative position.

With the above and other objects in view, our invention resides in thenovel features of form, construction, arrangement, and combination ofparts presently described and pointed out in the claims.

In the accompanying drawing Figure 1 is an exploded perspective view ofthe handle and blade holder of a disposable razor constructed inaccordance with and embodying the present invention;

Figure 2 is a perspective view of the disposable razor in operativeposition;

Figure 3 is a side view;

Figure 4 is a top plan view;

Figure 5 is a perspective view of the razor in inoperative position; and

Figure 6 is a modified type disposable razor handle constructed inaccordance with and embodyin the present invention.

Referring now by reference characters to the drawing which illustratespreferred embodiments of the present invention, A designates a razorhavin a handle i, fabricated preferably of a thermoplastic resin such asa polyacrylate, and being bent upon its longitudinal axis to provide apair of substantially parallel wall portions 2, 3, spaced from eachother by the bight 4 thereby formed. The outwardly presented or endportions of the walls 2, 3, are slightly curved toward each other forconvergence, as at 5, for reasons to be shown hereinafter, and adjacenttheir upper margins are cut away to provide inwardly extending recesses6, 7, respectively, having parallel upper and lower sides, which aredownwardly and outwardly inclined at an angle to a plane normal to thewalls 2, 3.

Provided for co-operation with the handle I is a blade holder 8, also,preferably, fabricated of a suitable thermoplastic resin such as apolyacrylate and having a length substantially equivalent to that of thehandle I and a thickness slightly in excess of the distance between theconverging ends of the walls 2, 3, of the handle I so that the saidblade holder 8 may, when not in use, be partially housed within thebight s of the handle I, being retentively gripped between the saidcurved ends of the walls 2, 3, as may best be seen in Figure 5. Theinherent resiliency or" the material of construction allows the saidconverging ends of the walls 2, 3, to yield sufficiently to permit theblade holder 8 to be withdrawn from, and inserted within, the bight i ina facile manner.

On its forward face, the holder 8 is provided centrally with alongitudinal, slot-like recess 9 extending from end to end, for snuglyreceiving a razor blade H], as by press or jam fitting, with its cuttingedge H being presented outwardly. Beneath the recess 9 the blade holder8 is integrally provided with a forwardly projecting portion l2 which isspacedly notched to provide a safety guard 13 for the blade [0. On itsnormally rearwardly presented surface the blade holder 8 is providedwith a pair of recesses l4, l5, spaced by a distance substantially equalto the bight 4 of the handle I for alignment with the recesses t, '1,respectively, and being dimensioned so that the walls thereof willtightly interlock with the portions of the walls 2, 3, of the handle Iinwardly of the recesses 6, 1, as may best be seen in Figure 3, formaintaining the blade it in operative position, wherein the upper andlower sides of the recesses 6, 7, will securely engage the upper andlower surfaces, respectively, of the blade holder 8.

It will be noted that with th blade holder 8 in operatively-engagedrelation with the handle i, it will assume an angle to a plane normal tothe walls 2, 3, coincident to that of the recesses 6, 1, whereby theblade [0 will be presented at a convenient and efiective attitude forshaving or cutting purposes.

Thus, as shown hereinabove, the blade holder 8 may be as readily andsecurely engaged within the recesses 6, 1, of the handle I for usage, asit may be housed retentively within the bight 4 of the said handle whennot in use, with the cutting edge ll of the blade It] being directedinwardly for protection. In inoperative condition, the blade holder 8and handle I provide a compact unit having negligible weight andrequiring a minimum storage space. The low cost of manufacture of therazor A makes same competitive with currently used razors, since thecost of blades therefor will approximate the cost of the razor A and,hence, same may be discarded after the blade H] has become dull.

If desired, a modified type of handle I, as illustrated in Figure 6, maybe made which is bent upon its longitudinal axis to form a pair ofsubstantially parallel walls 2", 3, spaced from each other by the bight4 formed thereby. Provided in the handle I adjacent the upper marginthereof is an enlarged aperture l6 which extends from substantially themidpoint of one wall 2' around the bent portion of the handle I tosubstantially the midpoint of the other wall 3. The upper and lowersides, of the said aperture it are downwardly and outwardly directed atan angle similar to that of the recesses 6, l, of the handle I, abovedescribed. The blade holdert is adapted for. engagement with the handleI in a like manner as with the handle all as set forth hereinabove.

It should be understood that changes and modifications in the form,construction, arrangement, and combination of the several parts of thedisposable razor may be made and substituted for those herein shown anddescribed without departing from the nature and principle of the presentinvention.

Having thus described our invention, what we claim and desire to secureby Letters Patent is:

1 A razor comprising a blade-holder having a back portion extending aftof the blade there-. of, and a resilient channel-shaped handle havingsomewhat converging flanges spaced so as to accommodate the thickness ofsaid back portion, the said handle being slotted transverse to the axisthereof, the width of such slotting being sufficient to receive thethickness of the back portion of said blade-holder, a pair of spacedtransverse notches formed in said back portion of the blade holder, the,said notches being of a width suiiicient to receive the thickness ofsaid flanges and being spaced from each other approximately the samewidth as the spacing of said flanges, so constructed and arranged thatthe blade-holder may be mounted on the handle by the mating of itsnotches with the slotted portions of the handle flanges and there heldse curely by the resiliency of said handle.

2. A safety razor comprising a blade holder including a guard portion, ablade grasping recess, and a back portion having a rear edge, a pair ofspaced notches in and perpendicular to the rear edge of said backportion, a detachable channel-shaped stowing handle of a length at leastequal to the length of the blade holder, formed of springy material andhaving slightly converging flanges spaced so as to receive graspinglythe upper and lower surfaces of the back portion of the blade holder forstowing the blade within the handle when not in use, and flange notchesacross the flanges, said notches being of a width sufficient toaccommodate snugly the thickness of the back portion of the blade holderand adapted to engage the spaced notches therein, the said spacednotches being so spaced as to bend the springy channel handleelastically whereby the bending resistance in the channel. handle urgesthe channel flanges graspingly against the blade holder notches and thussecures the blade holder in shaving position.
